BAKING-OVEN.

Specification of Letters Patent.

Application filed May 29, 1911.

Patented Oct. 10, 1911.

Serial No. 629,979.

To all whom it may concern:

Be it known, that I, JOSEPH MILLER, Jr., a citizen of the United States, residing at lVaterville, in the county of Lesueur and State of Minnesota, have invented certain new and useful Improvements in Baking- Ovens, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to baking ovens and has special reference to that class of baking ovens in which the heat of the oven is utilized for heating water or generating steam to be distributed fromthe oven.

Referring to the accompanying drawings Figure 1 is a view in perspective of a baking oven constructed in accordance with this invention. Fig. 2 is a view in vertical cross section looking from the rear of the oven. Fig. 3 is a slde view in longitudinal section of the oven. Fig. 1 is a view in horizontal section on the line XX, Fig. 2, looking upward from the bottom of the oven as indicated by the arrow in Fig. 2. Fig. 5 is a detail view in perspective of a water tank employed in connection with this invention. Fig. 6 is an enlarged detail view in longitudinal section of the water tank-shown in Fig. 5.

The oven constructed in accordance with this invention comprises a preferably rectangular structure formed with walls 1 of earthen-ware, brick, or other suitable non-- conducting heat material and with a top 2 preferably formed of brick covered with sand. The walls and top of the oven are sheathed with sheet metal 3, said walls being bound together and braced by means of transverse rods 4 held in place by nuts 5 and plates 5.

Located centrally in the front of the chamber formed by the structure just de scribed is a furnace 6 preferably consisting of an oblong rectangular box-shaped structure with an open top beneath which is the ash pit or chamber 7 separated from the furnace 6 by grate bars 8 having supporting cross rods 8.

Supported above the furnace 6 on a suitable frame 9 and mounted on the bars 6 is a water tank 10 preferably in the form of a U-shaped box closed at its sides and ends. Water is supplied to and circulated through side edges of the flooring 16.

the tank 10 by means of pipes 11 which lead from the structure to a building or other place to be heated and from which the water supply is obtained.

The ash pit, furnace, and place where the water tank is located are each provided with a suitable door 12. The ash pit and furnace are inclosed by side walls 13 and a rear wall 14 which extends only part way to the top of the furnace in order to form an opening for the escape of the products of combustion.

Located in the upper part of the chamber formed by the walls of the structure hereinbefore described and extending longitudinally from one end thereof are metallic T- bars 15 spaced apart from each other and having their ends supported in the front and rear walls of the structure. Supported upon these longitudinal T-bars 15 is a floor 16 of brick, earthen-ware or other suitable heat retaining material. Extending over said flooring to form a chamber is a sheet metal covering 17 which has curved downwardly depending sides 18 secured to the The front edge of the covering 17 abuts against the front wall of the structure in which is an opening 19 closed by a door 20. The rear end of the covering 17 is formed with a curved depending portion 21 which is secured to the edge of the flooring 16. The flooring 16 terminates at a short distance from the sides and rear wall of the structure so as to afford passages for the ascent of the products of combustion and the escape of the same to a discharge chimney 22. The covered portions 18 and 21 of the cover serve to guide the products of combustion in their passage upward and over the cover 17.

The oven constructed in accordance with this invention will be thoroughly heated by the products of combustion from the furnace beneath which surrounds the bake oven on all sides and which passes over the same in its passage to the chimney 22. By means of the arrangement of the water tank above the furnace the water supplied thereto and circulating through the same will be thoroughly heated and conducted to the place where it is to be used.

The front of the structure is provided with a pyrometer 28. Located adjacent to the top of the front wall of the structure are openings 2a serving as flue cleaners. Mounted on a shelf 25 behind an opening 26 in the front wall of the structure is an oven lamp 27.

What I claim is 1. In a baking oven of the kind described, a building forming a large chamber, a furnace mounted in the lower part of said chamber, a water tank mounted above said furnace, water circulating pipes connected to said tank leading to a point of supply and discharge, an open framework located above said furnace and Water tank, a bake oven mounted on said framework with passage ways at the sides and top thereof for the passage of the products of combustion, and an escape chimney in the top of said building communicating with said passage ways.

2. In a baking oven of the kind described, a building forming a chamber, a furnace mounted in said chamber, a water circulating tank located above said furnace, beams spaced apart from each other and extending across said chamber above said furnace and water tank, a baking oven mounted on said beams with passage ways at the sides and top of said oven for the passage of the products of combustion, and an escape chimney in the top of said building communicating with said passage ways.

3. In a baking oven of the kind described, a building forming a chamber, a furnace mounted at the lower part of said chamber, a water circulating tank mounted above said furnace, metallic beams spaced apart from each other and having their ends mounted in the walls of said chamber, a baking oven consisting of a floor of earthenware material and a sheet metal covering mounted on said beams with passage ways at the sides, one end and the top of said baking oven for the passage of the products of combustion, and an escape chimney in the top of said baking oven for the passage of the products of combustion, said escape chimney in the top of said building communicating with said passage ways.

4. In a baking oven of the kind described, a building having its walls and top formed of heat retaining material, a metallic sheathing on the outside of said, walls and top, a furnace located in the lower part of said chamber, a water circulating tank mounted above said furnace, metallic supporting beams extending from end to end of said chamber, a baking oven formed with an earthenware floor, and a metallic covering with curved sides and a curved end mounted on said beam, said oven being spaced from the sides and one end of said chamber to form passage ways, and an escape chimney communicating with said passage ways.

5. A baking oven of the kind described, consisting of a building forming a chamber, a rectangular casing in the front of and lower part of said chamber, an ash pit and furnace located in said rectangular casing, a framework mounted in said furnace, a circulating water tank mounted on said framework above said furnace, water circulating pipes connected with said water tank, metallic bars spaced from each other and mounted in the walls of said chamber above said water tank and furnace, a baking oven having an earthenware floor and a sheet metal top, and mounted on said metallic bars with passage ways at one end, and at the sides and top of said oven for the passage of the products of combustion, and an escape chimney in the top of said building communicating with said passage ways.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
